Gymnogyps californianus April 4, 1946 Pasadena, Cal., Area is conspicuous - much more on the west slopes I believe. April 6, 1945 Hopper Canyon, Cal. f. Drove up Pale Canyon road leaving Fillmore at 2 p.m. Fog at about 7500 ft. level and occasional sprinkling rain. Met T. Wole & H. Hill at Parking Place. They had procured a billy calf near Patricia (for $3) and, placed the fresh carcass in Big Meadow near the blind there. They said they had seen what they took for 2 condors in the Big Cave area + possibly two others in trees. They had seen no condors nearby. Earlier in the day it had sprinkled & occasionally been foggy. They had visited the old horse carcass at head of Hopper Canyon & flushed a few ravens & turkey vultures from it. The fog closed in & light rain commenced about 3:30 p.m. Hill & Wole drove down to Fillmore & Santa Monica. I went to camp at head of Hopper Canyon. It rained & fogged. About 5:30 p.m. I visited the old horse carcass. There was a 12" opening in back of head & neck, an 18" hole around anus, & two 4" holes in abdomen. The thighs had been mostly consumed. Carcass still stinks muchly. There were many spots of whitewash about (100+) as from many
